BACKGROUND OF THE INVENTION

Frequent urination is the need to urinate more than you normally would. The urge can strike suddenly and can cause you to lose control of your bladder. It can feel uncomfortable, like your bladder is extremely full. Urologists, who are doctors that specialize in the urinary system, consider going more than 8 times in 24 hours to be frequent urination.

There are several instances that you need to visit bathroom. For example, a frequent need to wake up and go to the bathroom to urinate at night which is called nocturia. Nocturia is a common cause of sleep loss, especially among older adults.

Due to anatomical differences, men and women experience the urge to urinate for different reasons. Women generally experience it as a consequence of childbirth, menopause, and/or pelvic organ prolapse. In men, it can be directly attributed to benign prostatic hyperplasia (BM), also known as enlarged prostate. The urge to urinate can also be a symptom of other medical conditions including urological infection, a tumor of the bladder or prostate, a condition called bladder prolapse, or disorders affecting sphincter control. It is also common in people with heart failure, liver failure, poorly controlled diabetes mellitus, or diabetes insipidus. Diabetes, pregnancy and diuretic medications are also associated with frequent urination.

Nocturia

Most people without nocturia can sleep for 6 to 8 hours without having to urinate. Some researchers believe that one event per night is within normal limits; two or more events per night may be associated with daytime tiredness. Patients with severe nocturia may get up five or six times during the night to urinate. Nocturia can affect the sleep cycle which can lead to sleep deprivation, fatigue, drowsiness, and mood changes. It can also disturb the partner's sleep due to visiting the bathroom more often.

One in three adults over the age of 30 makes at least two trips to the bathroom every night. It can happen at any age while the majority of those who are dealing with nocturia are usually over the age of 60. Two in three women over age 40 wake up at least once each night because of a full bladder and nearly half of them make two or more nighttime trips to the bathroom. There are several causes of nocturia in women.

Sometimes, it can be treated by behavior modification like:

-   -   Restriction of Fluid Intake—Limiting the intake of fluids in the         evening results in a decreased amount of urine produced at         night.     -   Afternoon Naps—This can help reduce fluid build-up by allowing         liquid to be absorbed in the bloodstream. When awakening from a         nap, the patient can use the bathroom and eliminate excess         urine.     -   Elevation of Legs—Like naps, elevating legs helps redistribute         fluids so they can be reabsorbed into the blood stream.     -   Compression Stockings—Creating an effect similar to elevating         your legs, these elastic stockings exert pressure against the         leg while decreasing pressure on the veins. This allows fluids         to be redistributed and reabsorbed into the bloodstream.

Different medicinal options exist to alleviate and even treat nocturia. These may be used alone or combined with some of the behavioral modifications listed above, which has been proven to be more effective. However, studies have confirmed that medication works only as long as taken. Once off medication, relapses are quite common. Additionally, all medications have some side effects.

Several solutions have been proposed to manage nocturnal enuresis such as:

-   -   Mattress Covers—A variety of products exist to protect the bed         including vinyl, waterproof and absorbent mattress covers or         sheet protectors, which can make cleanup easier if bedwetting         occurs.     -   Absorbent Briefs—These products are a form of modified underwear         designed to absorb liquid, therefore preventing leakage. Both         reusable and disposable products are available.     -   Skincare Products—Many products exist to protect the skin from         irritation and soreness that occur when a person experiences         nocturnal enuresis. A range of soaps, lotions, and cleansing         cloths exist for various skin types.

These methods are either not effective, or have several disadvantages like smell, leaks and lack of sufficient storage capacity.

Overactive Bladder

Overactive bladder occurs because the muscles of the bladder start to contract involuntarily even when the volume of urine in your bladder is low. This involuntary contraction creates the urgent need to urinate. The urge may be difficult to stop, and overactive bladder may lead to the involuntary loss of urine (urge incontinence). If you have an overactive bladder, you may feel embarrassed, isolate yourself, or limit your work and social life. According to the American Urological Association, an estimated 33 million Americans have an overactive bladder. This affects about 40 percent of all women in the United States. Excessive caffeine, nicotine, artificial sweeteners, and alcohol may also irritate the bladder walls and can worsen frequent urination symptoms.

Management of overactive bladder often begins with behavioral strategies, such as fluid schedules, timed voiding and bladder-holding techniques using pelvic floor muscles. If these initial efforts don't help enough with overactive bladder symptoms, medications are usually advised.

In view of the foregoing, there is a need for devices, systems, and methods to eliminate the need to go to bathroom several times during the night by urination while in the bed during sleep which in turn improves the sleep cycle. This could eliminate the negative impacts of conventional treatments and management, and said devices, systems, and methods would be well received in the marketplace.

DETAILED DESCRIPTION

For the purposes of promoting an understanding of the principles of the present disclosure, reference will now be made to the embodiments illustrated in the drawings, and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of this disclosure is thereby intended.

An objective of the present invention is to provide a non-invasive means of treating urinary dysfunction. The goals of the embodiments herein are to isolate urethral and vaginal openings to prevent any urine leak to the vagina during urination, be non-occlusive of the vagina, provide means of collecting urine with minimum amount of skin contacted by urine, and to be comfortable to the patient. Furthermore, the embodiments are universal such that one size and configuration fits most women and need not be custom made. The embodiments are also useful when the patient is walking, standing, seating, reclining or sleeping.

Although the disclosed devices, systems and methods of the present disclosure are presented in the context of treating a patient for sleep disorders such as nocturia, enuresis and overactive bladder, the context presented is not intended to be limiting. For example, it is envisioned that the subject of the present disclosure may be used to treat any patient who has difficulty moving to a toilet and urinate. It is further envisioned that the disclosed devices, systems and methods may be used to assist any user in any situation where urinating in a toilet is inconvenient for any reason. It is further envisioned that the disclosed devices, systems and methods may be used to assist any user in any situation where a toilet is not accessible for any reason such as driving in a car. In this scenario the storage bag is attached to the leg or other body part.

The words proximal and distal are used in the disclosure to refer to components of the device 10 located closer to the patient and farther from the patient, respectively.

A primary objective of the devices, systems and methods of the present disclosure is to eliminate the need to awaken and use the bathroom while sleeping. The devices and methods herein help prevent interruption of the sleep cycle and also eliminate soiling of bed sheets from sleep disorders such as nocturia or enuresis. This device also prevents older patients from accidentally falling due to loss of control while going to toilet. The device additionally addresses many of the issues of conventional treatments of sleep disorders, such as medicinal treatments which must be used continually to be effective. As a result of using the embodiments herein, the patient's quality and duration of sleep is improved. As an added benefit, the device also aids in keeping the patient's sleeping area sanitary, thereby improving the cleanliness and comfort of the patient's sleeping conditions.

Another of objective of the devices, systems and methods of the present disclosure is to avoid frequent visits to toilet at other times while the patient is not in bed. In this scenario, the mobile version of the device should be used where the storage bag is strapped around the leg or otherwise attached to the body.

A first embodiment of an exemplary device 10 of the present disclosure for women comprises the components such as according to the configuration shown in FIG. 1. The figure shows the schematic of the device 10 which comprises at least of three components: 1) receiving cup 11 connected to the genital part of the body, 2) discharge tube 13, and 3) storage bottle 15 for storing urine.

The receiving cup (pouch) 11 is configured such that it may attach securely to the genitals of the user in a fluid-tight manner. Where the embodiment is configured for the female anatomy, the receiving cup is sized to encompass the urethra only and avoids encapsulating the vagina. A cup 11 for use on female genitalia does not comprise a protrusion for housing male genitalia and is shallow having a low natural profile. The receiving cup 11 is operably connected to a proximal end 43 of a discharge tube 13, and the two are in fluid communication with each other. The discharge tube 13 connects the receiving cup 11 to the storage bottle 15. The storage bottle 15 is connected to the distal end 41 of the discharge tube 13. The storage bottle also comprises an air vent 19.

In the embodiment of FIG. 1, the receiving cup 11 is sized and configured such that it encompasses only the urethra opening. This ensures the urethra opening is isolated from the vagina opening and it eliminates the possibility that bacterial strains in urine may enter the vagina. The receiving cup is attached to the urethra area by an adhesive 51 material. The adhesive material should be chosen not to produce allergic or other adverse effects to the patient. One option is to use thermally reversible glue. The glue may be reversible, thermo-responsive poly(N-isopropylacrylamide) (PNIPAM). It is in liquid state at room temperature and becomes solid at body temperature. Another option for the adhesive material could be Hollihesive which is manufactured by Hollister Company. The material of the receiving cup could be silicone or any other bio-material with similar properties.

The receiving cup 11, discharge tube 13, and storage bottle 15 of the device 10 may be three inseparable sections of a single component or, as in FIG. 1, may also be three separable components. The receiving cup may a single component that fits over the genitals forming a leak-free seal. If separable components, they may be connected in any suitable fashion, such as with couplings, and the connections are preferably also fluid-tight. For example, the discharge tube 13 may be connected to the receiving cup 11 and the storage bottle 15 by snap coupling connectors 17 which are leak proof and can easily be uncoupled. It is also preferable that the entire device 10 is fluid tight such that urine enters the receiving cup 11 and passes through the discharge tube 13 into the storage bottle 15.

A clip 49 is installed near the proximal end 43 of the discharge tube 13 to be connected to the clothing of the proximal end 43 thus isolating any body movement from the rest of the device 10. This aids in retaining the connection between the receiving cup 11 and the proximal end 43 of the discharge tube 13.

The discharge tube 13 may be of a flexibility and firmness that such that the patient's movement will not break or crush the discharge tube 13. It could also be disposable due to its low cost. The length of the tube should be such that, in addition to reaching the storage bottle 15 located at the bed side, is has enough slack for the patient's movement. This may be achieved by utilizing accordion type tubing. Accordion type tubing may be ridged and able to collapse longitudinally to become shorter while still allowing fluid passage. The discharge tube may consist entirety or mostly of the accordion type tubing. The discharge tube should also be anti-kinking to assure smooth flow during urination. Anti-kink tubing may be thicker, or reinforced such as to be stiffer as opposed to tubing that may kink due to patient movement.

In a preferred embodiment, the receiving cup 11, the storage bottle 15 and discharge tube 13 may be reusable, or alternatively may be disposable and for one time use, or alternatively, the receiving cup may be disposable and the other two components resusable. All the non-disposable components have to be washed daily.

The storage bottle 15 may have a capacity as large as one liter, and can be a hard bottle, such as a glass bottle, or alternatively may be a flexible container and made from a plastic material. During use, the storage bottle 15 is preferably located near the bed side when the patient is in the bed and is preferably strapped around the leg or otherwise attached to the body at other times. The bottle is equipped with a one-way valve 21 to vent the air as urine enters the bottle. This valve is leak proof to ensure any undesirable odors remain in the bottle.

Also shown in FIG. 1 is an optional one-way valve 21 operably connected to the discharge tube 13 near the proximal end 43. The one-way valve 21 could also be connected to the receiving cup 11. The one-way valve 21 prevents backflow of urine while the device is in use.

Pictured in FIG. 2A is an embodiment of the present invention intended for use on patients having male genitalia. Like the embodiment illustrated in FIG. 1, the device 10 of FIG. 2A comprises a receiving cup 11, discharge tube 13 and storage bottle 15. One-way valves may also be included. The device 10 may also comprise leak-proof connectors such as snap couplings connectors or barbed fitted connectors 17. Embodiments described below intended for use on male genitalia share many of the features of the embodiment described above.

As mentioned, the receiving cup of a device intended for male anatomy may be sized differently than a device sized for female anatomy. FIG. 2A depicts the receiving cup 11 of an alternate embodiment of the present invention. In this embodiment the receiving cup 11 is made of a compliant material like silicone. The receiving cup 11 is further formed to cover the genitals including the penis 27 and testicles/scrotum 25. The shape of the receiving cup 11 resembles a glove having a proximal area, a “palm,” configured to fit the testicles/scrotum and a smaller distal area, a centrally positioned “finger,” 29 for configured to fit the penis. During use, the patient's penis 27 rests inside the finger 29 of the receiving cup 11 and the testicles will rest inside the palm 33 of the glove. The distal end 31 of the finger 29 opens to a short tube which couples to the discharge tube 13 by way of a snap coupling connector 17. There is a one-way valve 21 at the outlet of receiving cup 11 that connects to the discharge tube 13. The receiving cup 11 in this configuration is leak proof all around its edge due to the use of suitable adhesive material. PNIPAM is an exemplary adhesive that may be used. Adhesive may be used on the proximal edge of the cup where it contacts the patient to securely fasten the cup.

FIG. 2B depicts another embodiment of a receiving cup 11 intended for use with male genitalia. In this embodiment, the receiving cup 11 is made of a compliant material like silicone and is connected to a discharge tube 13. The receiving cup 11 is comprised of a material that is leak proof and does not create discomfort to the patient during use. The receiving cup 11 may take a generally cylindrical shape and resemble a condom which the individual can wear. In an embodiment, the cup may extend partially along the penis, such as midway, or further or less, ending along the shaft. The cylinder may comprise openings at both ends, the openings being larger at the proximal end and smaller at the distal to accommodate the penis 27 and the discharge tube 13, respectively. The receiving cup of this embodiment cup will fit over the penis 27 without covering the testicles.

FIG. 2C depicts an alternate embodiment of the device 10. In this embodiment, the receiving cup 11 is supported against the genitals via a support 39 similar to an article of underwear-like clothing. Any of the receiving cups described above can be used with the support 39. The support 39 preferably surrounds the hips and/or waist of the user. At least a portion of the device, such as the receiving cup or discharge tube, may protrude from the underwear/support. The protruding portion of the device will extend through an opening in the support. The support 39 is configured to hold the genitals in place and constrain genital movement. In another embodiment the receiving cup 11 is integral with the support 39 to comprise a single piece.

One exemplary method of using the device 10 while sleeping includes the steps of (where the device has three separate components):

The patient places the storage bottle 15 at the bed side and then connects the discharge tube 13 to the storage bottle 15. The patient then wears the receiving cup 11 after going to bed before lying down on the bed. The individual then connects the other end of the discharge tube 13 to the receiving cup 11. Finally, the individual connects the clip 49 installed near the proximal end of the discharge tube 13 to the clothing such as underwear or pajamas to isolate any body movement from the rest of the device 10.

A similar method may be used with other embodiments of the device. Other exemplary methods may further comprise steps such as adhering the receiving cup to the patient, wearing a support garment over the receiving cup, urinating into the receiving cup, collecting excreted urine in the storage bottle, detaching the storage bottle to empty the bottle.

The advantage of this device is that the individual can urinate anytime without arousing from sleep. The device is very low cost and simple to assemble and disassemble. It may take the individual several days to get used not waking up to urinate.

This device/method can have a mobile embodiment where individuals can wear the device 10. This is particularly applicable for those who have to urine frequently as often as half an hour for some individuals. The storage bottle 15 form can be long and slim and attached around the leg with a strap 47. One embodiment of the storage bottle is shown in FIG. 3. The rest of the apparatus will be the same as the stationary version. In this embodiment the discharge tube 13 could be attached to the individual's thigh with an adhesive tape.

While various embodiments of devices and systems for treating frequent urination and methods for using the same have been described in considerable detail herein, the embodiments are merely offered as non-limiting examples of the disclosure described herein. It will therefore be understood that various changes and modifications may be made, and equivalents may be substituted for elements thereof, without departing from the scope of the present disclosure. The present disclosure is not intended to be exhaustive or limiting with respect to the content thereof.

Further, in describing representative embodiments, the present disclosure may have presented a method and/or a process as a particular sequence of steps. However, to the extent that the method or process does not rely on the particular order of steps set forth therein, the method or process should not be limited to the particular sequence of steps described, as other sequences of steps may be possible. Therefore, the particular order of the steps disclosed herein should not be construed as limitations of the present disclosure. In addition, disclosure directed to a method and/or process should not be limited to the performance of their steps in the order written. Such sequences may be varied and still remain within the scope of the present disclosure. 

1. A device for portable urine collection comprising: a receiving cup; a discharge tube having a proximal end and a distal end; and a storage bottle; wherein the receiving cup is connected to the proximal end of the discharge tube and the storage bottle is connected to the distal end of the discharge tube.
